反応手順
Then, 8.47 g of 4-bromo-2-trifluoromethylphenol, 5.34 g of potassium carbonate, 4.49 g of benzyl chloride and 100 ml of N,N-dimethylformamide were charged into a reaction vessel, and stirred under ice cooling. After 24 hours, the reaction solution was poured into ice-water and extracted three times with 50 ml of diethyl ether. The ether layers were combined, washed with an aqueous 10 % sodium hydroxide solution, dried over anhydrous magnesium sulfate and then concentrated to give a crude product. This crude product was subjected to silica gel chromatography to give 9.38 g of 4-bromo-2-trifluoromethyl-1-benzyloxybenzene, (yield, 81%).
